Description
TECHNICAL FIELD

Embodiments of the present disclosure relate to systems and methods for receiving and propagating efficient search updates in real time. More particularly, embodiments of the present disclosure relate to enabling users to order items online and deliver the items, by receiving and propagating efficient search updates in real time to a user device.

BACKGROUND

Users (e.g., online customers, online merchants, delivery personnel) often use online website portals or mobile applications to order items (e.g. order food, grocery). By way of example, users maintain profiles including their information (e.g. location information, menu, name) at the online websites. In a situation where a user modifies their profile information, there is a significant time delay or time difference from when the modification was made to when the modification is reflected on an online website portal. As a result the delay in reflecting the modifications, causes inconvenience to the users.

By way of example, when a restaurant updates their online menu contents (e.g. dish name, price of a dish, restaurant hours, etc.) by using an online website portal for a food ordering website, then the change in the online menu would be reflected on the food ordering website after a significant time delay. Current solutions that are utilized for such update processes are not real time as these update requests are processed in batches. Requests are processed by network servers at regular time period, such that, the requests received during those time periods are processed together as a batch, at the end of the time period. Processing of updates by the network servers in batches, results in a significant time delay in reflecting the updates to the users. Accordingly, current solutions are inefficient and generate delays, thus there is a need to reflect updates in real time.

For example, the name of merchant store 112(1) may be a parent entity, while the store hours, menu name, photo album, address location, etc., are child entities that are stored under the parent entity. Further, menu information includes a plurality of categories, which includes Appetizers, Salads, Mexican cuisine, Entrée, Deserts, etc these entries would be categorized as child sub entities under the menu name child entity. For example, merchant profile information may include store hours as 8:00 am to 5:00 μm, for the merchant store 112(1). A merchant of Item service provider device 110(1) modifies store hours from 8:00 am to 5:00 pm to new timings of 9:00 am to 6:00 pm. This modification causes an update in store hours entry at the remote database 120 for the merchant store 112(n). This update of store hours entry at the remote database 120 is determined by domain services module 210 based on monitoring the remote database 120. Similarly, multiple modifications may be performed by each of a plurality of merchants, customers and/or drivers in their corresponding merchant profile information, customer profile information and/or driver profile information to result in multiple entity change request to be generated.

By providing a hierarchical structure this technology provides technical advantages of an optimized process that reduces data overhead. By providing a hierarchical structure this technology identifies a specific location where a modification is made, and thus generates an entity change request that includes information directed to updating the search index database 220 information associated with only that parent entity, child entity, and/or child sub entity that has been modified, instead of generating an entity change request to update entire menu information upon a change in a child sub entity, which requires extra data overhead.

In step 404, entity change listener module 212 of integration server system 116 receives a first entity change request upon modification of an entry in remote database 120. Upon determining modification of an entry in step 402, domain services module 210 transmits a first entity change request. The first entity change request includes information corresponding to the entity that has been modified. By way of example, when a price associated with an item within an Appetizer category of a menu is modified, then the first entity change request would include an entity identifier associated with the child sub entity of Appetizer category and the modification information which in this example is the, price associated with the item within the Appetizer category. Further, the entity identifier may be an address within a lookup table stored in the search index database 220. As shown in FIG. 5 step 502.

In another example, when merchant modifies store hours information for merchant 112(1), a domain services module 210 monitors remote database 120 (as explained in step 402) and upon determining a modification of a data entry, domain services module 210 transmits a first entity change request. The first entity change request includes an identifier associated with the child entity of store hours and the modification information which in this example, is the change in hours from 8:00 am to 5:00 pm to new timings of 9:00 am to 6:00 pm. Similarly, a plurality of merchants, customers and/or drivers in the corresponding merchant profile information, customer profile information and/or driver profile information respectively over the time period for which the transaction listener module 214 receives the pushed data from the entity change storage 222. The customer devices 102(1)-102(n), item delivery provider devices 106(1)-106(n), item service provider devices 110(1)-110(n) and remote database 120 may be referred to as an external system.

In step 406, entity change listener module 212 of integration server system 116 stores the modification made to the entry in an entity change storage 222. Storing is also referred to as saving the modification made to the entry in an entity change storage 222. Upon receiving the first entity change request, the integration server system 116 stores the identifier associated with the entry that has been modified and the modification information included in the first entity change request. By way of example, when the first entity change request identifies the entry to be modified as a price of an item within an Appetizer category of a menu, then the integration server system 116 stores the entity identifier associated with the child sub entity of Appetizer category and the modification information which in this example is the price associated with the item within the Appetizer category in the entity change storage 222. Similarly, the identifier associated with the entry that has been modified and the modification information in entity change requests generated based on multiple modifications performed by the plurality of merchants, customers and/or drivers in their corresponding merchant profile information, customer profile information and/or driver profile information are also stored in the entity change storage 222. As shown in FIG. 5 step 504.

In step 408, domain services module 210 of integration server system 116 transmits a commit event request to initialize a transaction listening mode at transaction listener module 214. Domain services module 210 generates a commit event request upon transmitting of the first entity change request in step 402. This is depicted in step 506 of FIG. 5.

In step 410, entity change storage 222 of integration server system 116 pushes the data stored in step 406 to transaction listener module 214. Transaction listener module 214 of integration server system 116 initializes a transaction listening mode upon receiving the commit event request from domain service module 210. Upon initialization of transaction listening mode, transaction listener module 214 waits to listen for data to be received from entity change storage 222. Entity change storage 222 pushes the data stored in step 406 to transaction listener module 214. Transaction listener module 214 identifies entity identifiers and corresponding modification information from the received data. The pushing of the data from entity change storage 222 is performed in real time. In some embodiments, as soon as the data is stored in entity change storage 222, the data is immediately pushed to transaction listener module 214. A plurality of identifiers associated with the entries that are changed and the corresponding modification associated with those entries is pushed by entity change storage 222. Similarly, data pushed to the transaction listener module 214 and stored in the entity change storage 222 may include a plurality of modifications made by a plurality of merchants, customers and/or drivers in the corresponding merchant profile information, customer profile information and/or driver profile information respectively over the time period for which the transaction listener module 214 receives data from the entity change storage 222, as shown in step 508 of FIG. 5.

In another example, the pushing of the data from entity change storage 222 is performed at regular intervals of time periods. The time period may include 1 microsecond, 1 second, 5 seconds, 5 minutes, 1 hour and/or 24 hours, although any other time period may also be included. The data pushed from the entity change storage 222 includes a plurality of identifiers associated with the entries that are changed and the corresponding modification associated with those entries during the time periods.

In another example, transaction listener module 214 fetches the data stored in step 406 at the entity change storage 222. The fetched data may include an identifier associated with the entry that has been modified and the modification information included in the first entity change request. For example, the entity identifier associated with the child sub entity of Appetizer category and the modification information which in this example is the price associated with the item within the Appetizer category in the entity change storage 222.

Transaction listener module 214 identifies event type associated with entity identifier, upon receiving the entity identifier from the entity change storage 222, either by pushing of the data stored in step 406 by the entity change storage 222 to the transaction listener module 214 or by fetching of the data stored in step 406 at the entity change storage 222 by transaction listener module 214. Identified event type includes a location associated with the entity identifier in the hierarchical structure. By way of example, event type may include location associated with only that parent entity, child entity, and/or child sub entity that has been modified.

In step 412, transaction listener module 214 of integration server system 116, identifies a fire event in response to receiving the data stored in the entity change storage 222. A fire event is an event for generating a plurality of snapshots of data received from entity change storage 222. Transaction listener module 214 identifies initialization of a fire event in response to receiving the data stored in entity change storage 222. Initialization of a fire event causes transaction listener module 214 to generate a plurality of snapshots of the data received from the entity change storage 222 in step 410. Upon identifying the fire event, transaction listener module 214 of integration server system 116 generates snapshots of the data pushed by the entity change storage 222. By way of example, a snapshot is a copy of the data received from the entity change storage 222 by the transaction listener module 214 in step 410. In another example, a snapshot would be a database table that includes reference indicators to the data stored in the entity change storage 222. As shown in FIG. 5, step 510, two snapshots being transmitted via the 514 path and 516 path. These snapshots have the same data contents that are being transmitted.

In step 414, transaction listener module 214 of integration server system 116, transmits a request to clear the entity change storage 222. Upon receiving the data pushed by the entity change storage 222, the transaction listener module 214 transmits a request to clear the data that has been pushed by the entity change storage 222. Upon receiving the request to clear the data, the entity change storage 222 deletes the data that has been pushed. This is depicted in step 512 of FIG. 5.

In step 416, transaction listener module 214 of integration server system 116, transmits one of the snapshots along with the corresponding event type identified in step 410 to cache event publisher module 216. The cache event publisher module 216 then stores the snapshot data in cache database 224. When a request to access the modified merchant profile information, customer profile information, and/or driver profile information from search index database 220 is received, and if the search index database 220 is overloaded and is not available to provide the data immediately, in this scenario, the snapshot stored in the cache database 224 is then utilized to facilitate the request. The request is serviced by the snapshot data stored at the cache database 224. As shown in FIG. 5 step 514, a first one of the snapshots is transmitted to cached event publisher module 216.

In step 418, transaction listener module 214 of integration server system 116, transmits the snapshots to a search event publisher module 218. Search event publisher module 218 stores the snapshots. As shown in FIG. 5 step 516, a second one of the snapshots along with the corresponding event type identified in step 410 is transmitted to search event publisher module 218.

Proceeding to FIG. 4B, in step 420, search event publisher module 218 of integration server system 116, the search event publisher module 218 utilizes the event type received along with the snapshot to determine a location associated with the modified entity. Based on the determined location the search event publisher module 218 classifies the data entries in the snapshot into a one of a plurality of data pipeline categories. Search event publisher module 218 is a streaming service that classifies the data entries in the snapshot into multiple streams based on the type of category and forwards it along the streams to data pipeline categories. The pipeline categories include parent entity associated with one of a merchant stores 112(1)-112(n). By way of example, the pipeline category 526 may be associated with a merchant store 112(1), the pipeline category 528 may be associated with a merchant store 112(n). Based on the type of location identified in the event type, the search event publisher module 218 determines one of the data pipelines 526-530 corresponding to be as the location identified in the event type and transmits the data entry to the corresponding one of the data pipelines 526-530.

In another embodiment, pipeline categories include parent entity, child entity, child sub entity, although any other categories may also be included. By way of example, the data pipelines 526, 528 and 530 of FIG. 5 may be a parent entity data pipeline 526, child entity data pipeline 528 and child sub entity data pipeline 530 [not shown in FIG. 5]. Search event publisher module 218 transmits data entries classified as parent entity in step 420 as a first stream to a parent entity data pipeline 526, further search event publisher module 218 may transmit a second stream of a child entity data pipeline 528 for data entries classified as child entity and search event publisher module 218 may transmit a third stream of a child sub entity data pipeline 530 for data entries classified as child sub entity. Merchant profile information is stored, in a hierarchical structure. For example, the name of merchant store 112(1) may be a parent entity, while the store hours, menu name, photo album, address location, etc., are child entities that are stored under the parent entity as child entities. In this example, the name of merchant store 112(1) is a parent entity. Store hours, menu name, photo album, address location, etc., may be child entities that are stored under the parent entity. Further, menu information may include a plurality of categories, which includes Appetizers, Salads, Mexican cuisine, Entrée, Deserts, etc. these entries may be categorized as child sub entities under the menu name child entity. In another example, pipeline categories include Appetizers, Salads, Mexican cuisine, Entrée, Deserts.

In step 422, search event publisher module 218 of integration server system 116, identifies where within the hierarchical structure a particular modification has been made and categorizes that data entry to be a parent entity, child entity or sub child entity based on where the modification was made. Upon identifying the category associated with the data entry, search event publisher module 218 transmits each of the data entries in a corresponding data pipeline that is classified into based on the classification performed in step 420. As one example, in step 420, search event publisher module 218 identifies the type of location based on the event type, the search event publisher module 218 determines one of the data pipelines 526-530 corresponding to be as the location identified in the event type and transmits the data entry to the corresponding one of the data pipelines 526-530. When search event publisher module 218 identifies the location associated with the data entry based on the event type corresponds to a location in the data pipeline 526, then the data entry is transmitted to data pipeline 526 by the search event publisher module 218. As another example, in step 420, search event publisher module 218 may identify that a received entity change comprises modifying store hours from 8:00 am to 5:00 pm to new timings of 9:00 am to 6:00 μm. In response, search event publisher module 218 identifies that the data entry of store hours is a child entry data and accordingly transmits the identifier of store hours and the modification information associated with the store hours, which in this example is, modifying the time from 8:00 am to 5:00 pm to new timings of 9:00 am to 6:00 pm, to the child entity data pipeline 528. Similarly, data entries classified as parent entity would be transmitted over 520 to the parent entity data pipeline 526 by the search event publisher module 218, and data entries classified as child sub entries would be transmitted over 524 to the child sub entry data pipeline 530 by the search event publisher module 218.

In step 424, the search index database 220 of integration server system 116 receives the classified data from parent entity data pipeline 526, child entity data pipeline 528 and/or child sub entity data pipeline 530 over the flow 532. Search index database 220 receives the data from the parent entity data pipeline 526 and updates the data entry associated with the parent entity. Similarly, search index database 220 receives the data from the child entity data pipeline 528 and updates the data entry associated with the child entity. Similarly, search index database 220 receives the data from the child sub entity data pipeline 530 and updates the data entry associated with the child sub entity.

In step 426, search index database 220 of integration server system 116, receives a user search request to access data entry from within merchant profile information, customer profile information, and/or driver profile information. Upon receiving the user search request search index database 220 provides a response to include search results associated with the modified data entry updated in step 424 corresponding to the data entry included in the user search request.

FIG. 6 shows an alternate embodiment of FIG. 5 that contains a flow diagram illustrating an exemplary process of FIGS. 4A and 4B. FIG. 6 illustrates domain services module 210, entity change listener module 212, entity change storage 222, transaction listener module 214, and search publisher module 218, of server device 200 in this example. In this example embodiment, these modules are implemented as event processing system 602. Further, event consumer module 226, event handler module 227, generate event entity 228, event publisher module 229, merchant application programming interface (API) 230, cache database 224, cache event publisher module 216, search event publisher module 218, and search index database 220, of server device 200 in this example are implemented as database system 604. In some embodiments, event processing system 602 and database system 604 are part of integration server system 116.

In accordance with process 400 (FIGS. 4A and 4B) and FIG. 5, steps 602 is substantially similar to step 502. Step 604 is substantially similar to step 604. Step 606 is substantially similar to step 506. Step 608 is substantially similar to step 508.

In some embodiments, step 610 is substantially similar to step 510. In other embodiments, when, transaction listener module 214 of integration server system 116, identifies a fire event in response to receiving the data stored in the entity change storage 222. A fire event is an event for transmitting the data received from entity change storage 222 to search event publisher module 218. Transaction listener module 214 identifies initialization of a fire event in response to receiving the data stored in entity change storage 222. Initialization of a fire event causes transaction listener module 214 of integration server system 116, to transmit the received data to a search event publisher module 218 depicted in step 610. In step 612, transaction listener module 214 of integration server system 116, transmits a request to clear the entity change storage 222. Upon receiving the data pushed by the entity change storage 222, the transaction listener module 214 transmits a request to clear the data that has been pushed by the entity change storage 222. Upon receiving the request to clear the data, the entity change storage 222 deletes the data that has been pushed.

Search event publisher module 218 stores the received data from the flow 610 and then proceeds to determine if the received data includes data that has been modified, as depicted in step 614. Here, search event publisher module 218 compares the received data with corresponding data previously stored on the search event publisher module 218 to determine if data has been modified. When search event publisher module 218 determines that the received data does not include data that has been modified, then the method proceeds to flow 616 and the method ends here. However, when search event publisher module 218 determines that the received includes data that has been received modified then the data that has been modified is transmitted to event consumer module 226 as depicted by flow 618. Event consumer module 226 proceeds to determine if there is a matching event type based on received data depicted by flow 620. Event consumer module 226 determines if the received data has been identified to be modified matches with an event type. Event type may include a modification of a parent entity, child entity, or sub child entity based on identifying where the modification was made in the data that has been identified to be modified. Upon identifying the event type, e.g. the modification to be made at a child entity, then event consumer module 226 transmits the data that has been identified to be modified to event handler module 227, as depicted by flow 622. Event handler module 228 then updates a merchant application programming interface (API) 230 to and get updated data to reflect the modification made, as depicted by flow 624. Upon updating the merchant API 230, the event handler module 227 then proceeds to transmit the data that has been identified to be modified to generate event entity module 228, as depicted by 626. Generate entity module 228 then generates multiple snapshots of the data that has been identified to be modified. By way of example, a snapshot is a copy of the data that has been identified to be modified in step 410. In another example, a snapshot would be a database table that includes reference indicators to the data stored in the entity change storage 222. Multiple snapshots refers to multiple copies of the same data that has been identified to be modified. Generate entity module 228 then transmits the multiple copies of the same data that has been identified to be modified to the event publisher module 229. Event publisher module 229, transmits one of the snapshots to cache event publisher module 216 via flow 630. The cache event publisher module 216 then stores the snapshot data in cache database 224. Event publisher module 229 also transmits, a second one of the snapshots to search event publisher module 218.

Search event publisher module 218 of integration server system 116 identifies where within the hierarchical structure a particular modification has been made and categorizes that data entry to be a parent entity (e.g. store information), child entity (menu information of the store) or sub child (store open hours, store open information during holidays, store irregular hours during holidays) based on where the modification was made. In this example, store information is associated with data pipeline 636b, menu information of the store is associated with data pipeline 638b, and store open hours information is associated with data pipeline 640b, store open information during holidays is associated with data pipeline 642b, and store irregular hours during holidays is associated with data pipeline 644b. Upon identifying the category associated with the data entry, search event publisher module 218 transmits each of the data entries in a corresponding data pipeline that is associated with that category into based on the classification performed. Further, search event publisher module 218 may transmit the modified data entries corresponding to information of the store via flow 636a to data pipeline 636b. Search event publisher module 218 may transmit modified data entries corresponding to menu information of the store via flow 638a to data pipeline 638b. Search event publisher module 218 may transmit modified data entries corresponding to store open hours information via flow 640a to data pipeline 640b. Search event publisher module 218 may transmit modified data entries corresponding to store open information during holidays via flow 642a to data pipeline 642b. Search event publisher module 218 may transmit modified data entries corresponding to store irregular hours during holidays via flow 644a to data pipeline 644b. Further, step 646 is substantially similar to step 532.

The disclosed embodiments provide an improved method of receiving and propagating efficient search updates. By providing technical advantages of an optimized process of reducing data overhead and providing a real time process of search updating. As this technology provides a real time search updating process by pushing of data stored in entity change storage, this technology provides a fast and reliable process of reflecting modifications made to a database, which results in faster time displaying of modifications as part of search results. Thus, this technology reduces delays caused during updating of data entries. Further, this technology identifies a specific location where a modification is made, and thus generates an entity change request that includes information directed to updating a search index database information associated with only that parent entity, child entity, and/or child sub entity that has been modified. Thus, this technology reduces data overhead, instead of generating an entity change request to update entire menu information upon a change in a child sub entity, which requires extra data overhead.

In contrast, in the prior art, other strategies that have been implemented are inefficient as they require extra data overhead, which may not be beneficial to efficiently utilize network resources and thus increase network load. Further the prior art causes significant delays during a search updating process, while the disclosed embodiments provides a real time update process, that reduces delays between reflecting modifications made to data entries.
